In his quest to recruit talents to assist him, Duke Xiao promises to share Qin with anyone – including foreigners – who could help him realise his grand ambitions.

After discussing for three days and three nights on end, the two men develop a close relationship and work together over the next two decades to push forth a series of groundbreaking sociopolitical reforms in Qin.
